Turkey's tallest peak (6)
I believe the answer is:
ararat
'turkey's tallest peak' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for ararat that I've seen before include "original dry dock" , "Ark's supposed resting place" , "Highest mountain in Turkey" , "Mount where Noah's Ark came to rest" , "Biblical mountain" .)
